Unlikely, given how much money is at stake in both directions. E.U. citizens spent nearly 7.3 billion pounds visiting the U.K. in 2015, and countries such as Spain and Greece will resist anything that hit their tourism businesses. Still, May’s insistence on a hard Brexit theoretically risks the need for visas to even neighbouring France. The E.U. has in recent years worked towards abolishing visas rather than introducing them, not least to support its tourism industry.
